To all whom it may concern:

Be it known that I, Gnns rnn COMSTOCK, a citizen of the United States, residing in Brooklyn, in the county of Kings and State 'of New York, have invented certain new and useful Improvements in Impact and Reaction Motors, of which the following is a specification.

This invention relates to motors or rotary engines, and it consists substantially in the improvements hereinafter particularly described.

The invention has reference more especially to m0- tors or rotary engines of that class or character Which are driven or propelled both by direct impingement and reaction of charges of steam or other expansible propulsive agent; and the principal object of the invention is to provide such a motor which is thoroughly reliable and effective in operation, besides being comparatively simple in the construction and organization of parts oryelements constituting the same.

A further object is to provide a motor of the kind referred to which is economical both in its production and expenditure of energy; and one in which there is practically no waste or leakage, and in which inertia is readily overcome both in the stopping and starting of the same.

. Other objects of the inventionwill hereinafter more fully appear when taken in connection with the accompanying drawings in which Figure 1, is a vertical side elevation of my improved impact and reaction-motor as it appears when constructed for operation; and Fig. 2, is a vertical longitudinal sectional view thereof, showing parts removed and the shaft broken off at the ends. Fig. 3, is a part vertical transverse sectional elevation of Fig. 2. Fig. 4, is a horizontal sectional plan view of the casing and interior construction, certain parts being cut out to more clearly indicate the organization. Fig. 5, is a sectional detail view in perspective to more clearly indicate the construction and organization of the means for effecting the propulsion of the wheel both by direct impingement and reaction of charges of expansible propulsive agent thereupon. Fig. 6, is a similar view to Fig. 4, with the section taken in a different plane, and illustrating more clearly the lateral courses taken by the separate portions of each charge of expansible propulsive agent employed. Fig. 7, is an enlarged horizontal sectional view in detail; and Fig. 8, is a separate view in perspective of each of the several parts constituting the means for effecting the propulsion of the motor, said parts being shown substantially in the relation they bear to each other when properly assembled or combined.

Before proceeding with a more detailed description it may be stated that my improved impact-motor com-' prises means whereby on admission of charges of an expansible propulsive agent to the motor such charges are caused to flow laterally of the central plane of retation of the impactfivheel, and the construction and organization of the parts of the motor are such that each charge in transit serves to rotate the impact-wheel both by direct impingement and reaction thereupon. To effect this operation I employ a casing of special interior embodiment, and an impact-wheel also of special embodiment, the two cooperating in an efficient manner to utilize the full force of the charges of expansible propulsive agent without tendency to interruption of the speed of the motor.

Specific reference being bad to the accompanying drawings by the designating characters marked thereon, A, represents the casing of my improved impact-motor, the same being stationary and mounted upon a pillar or standard a, having a base b, the said casing comprising a cylinder 0, having secured to each end thereof, by means of bolts d, a head or disk 0, each of which is formed centrally with a sleeve or stuIling-box f, having a gland g, said latter elements forming bearings for a shaft B, extending through the motor, as shown. Mounted centrally of said shaft, with the ends thereof in working contact with the inner ends of said sleeves or stufling-boxes f, is the hub h, of an impact-wheel 0, having a rim 2, and preferably a connecting web 3, between the rim and hub, said rim being considerably less in diameter than the diameter of the cylinder 0, of the casing, and said web having openings l, therein forming communicatipn between the spaces m, 'm, on either side of the web within the rim, said spaces together constituting an exhaust-chamber for the propulsive agent, after expenditure of its force, a suitable outlet-pipe n, for the exhaust being fitted in one of the heads or disks 6, and leading from said chamber. Instead of the web 3, I may employ suitable spokes for connecting the rim with the hub of the impact-wheel, as is apparent, and I may also otherwise construct said wheel without departure from my invention. Fitted rigidly upon the outer surface of the said rim 2, at the center thereof, is a ring 5, having pockets formed therein at intervals of its outer surface all around, the walls 6, of each of said pockets being preferably parallel to each other and substantially tangential to said outer surface of the ring, see more particularly Figs. 3, and 5, and the walls of each succeeding pocket being inclined to the walls of the pocket preceding it. Also fitted or rigidly secured upon the outer surface of the rim 2, and on either side of said centrally disposed ring 5, is another ring 7, having in the outer surface thereof similar pockets, the walls 8, of which are flush or in alinement with the said walls 6, of the pockets of said ring 5; and secured to the rim in like manner, and to the outer side of each of said rings 7, is another ring 9, having in the outer surface thereof similar pockets, the walls 10, of which are also flush or in alincment with the walls of the pockets in each of the said rings 7. Still further'secured to theoutcr surface of said wheel-rim,

' and 7.

and to the outer side of each of said rings 9, is another ring 12, similarly constructed and arranged as the several rings already described, the walls of the pockets of each of these rings (12) being designated at 13. Fi nally, there is also secured to the outer surface of the wheel-rim 2, at the outer side of each of the said rings 12, a ring 15, the width of which is preferably considerably less than the width of either of the other rings described, and the depth or thickness of which is considerably greater than the depth or thickness of the said other rings, each of said outer rings 15, being formed with conduits or ports 16, leading outwardly from each of the pockets of said ring 12, see Figs. 5, 6, The outer edges of said rings 15, are in movable or working contact with adjacent portions of the inner surface of a cylinder 17, which is fitted in a stationary manner within the casing with the outer surface there of in contact with the inner surface of the cylinder 0, of said casing. Rigidly fitted to a portion of the inner surface of said cylinder 17 so as to inclose the ring 5, of the wheel-rim, is a centrally disposed ring 20, the outer surface of which is recessed circumferentially all around so as to form a continuous pressure-chamber 21, for an expansible propulsive agent, said pressurechamber being in communication through regularly located openings 22, in cylinder 17, with a continuous supplychamber 23, for such agent, formed in the inner surface of the said cylinder 0, said supply-chamber having in communication therewith the inner end of a supply-pipe 24, leading from a source (not shown) from which the expansible propulsive agent is derived. At regular or predetermined intervals thereof the body of said ring 20, is formed with injector-ports 25, the sides of which are inclined inwardly substantially at right angles to the walls of the pockets of the several rings hereinbefore described, said injector-ports extending all the way through such ring-body, as shown. The width of said ring 20, is substantially equal to the width of the said ring 5, and the inner surface of the ring 20, is formed with pockets corresponding in location and number with the pockets in ring 5, the sides 26, of the pockets of said ring 20, being also inclined and substantially parallel with each other. Also rigidly secured to the inner surface of the cylinder 17 of the casing, and at each side of the said ring 20, is a ring 27, the width of which is in excess of the width of each of the rings 7, and formed in the inner surface of each of said rings 27, all around is a series of pockets constructed precisely the same as the pockets in said ring 20, the walls of the pockets of these rings (27) being indicated at 28. Si milarly secured to the said inner surface of cylinder 17, and at the outer side of each of said rings 27, is still another stationary ring 29, the width of which is in ex cess of the width of each of the rings 12, and the inner surface of which is formed with pockets corresponding in number and position to the pockets of rings 20, and 27, the outer edges of said rings 29, having the adjacent surfaces of the rings 15, in working contact therewith, and the walls of the pockets therein being designated at 30. It will of course be unders'ood that the number of movable and stationary rings employed may be reduced or increased, as desired, and it will be seen that when the wheel is in position to have the pockets of the several rings thereof register with the pockets of the rings on the interior of the casing a number or series of chambers are thus formed extending from end to end of the inner structure. Seated in a circular recess 31, therefor in the inner face of each head or disk 6, of the casing is a stationary ring 33, formed with pockets constituted each of an inclined wall 34, and a straight radially disposed wall 35, said pockets corresponding in number to the pockets hereinbefore referred to in connection with the different movable and stationary rings employed, it being observed that the height of each of said recesses is in excess of the depth or thickness of each of said rings 33, thus leaving an open space all around the inner edge of said ring through which the spent charges of expansible propulsive agent pass into the exhaust-chamber m, m, and thence outwardly through the exhaust-pipe.

Located between the adjacent sides of each of the rings 7, and 9, on the rim of the wheel is a comparatively narrow ring 35*, the depth or thickness of which all around is equal to the depth or thickness of each of the rings first named, thus forming a partial or semi-par tition to the longitudinal chambers formed by the sides of the pockets of the two series of rings, as is apparent, each of said partitions being intermediate the sides of each of the stationary rings 27 of the cylinder 17; and similarly located between the adjacent sides of each of thesaid rings 9, and said rings 1.2, is another comparatively narrow ring 37, of equal depth or thickness with the first, and forming another partial or semi-partition for the said chambers, each of these latter rings occupying a position substantially intermediate the sides of each of the stationary rings 29, of cylinder 17 Located between the adjacent sides of each of the stationary rings 27 ,-and 29, of said cylinder 17, is also a comparatively narrow ring 40, the depth or thickness of which is about equal to the depth or thickness of said firstnamed rings (27 and 29), thus also forming a partial or semi-partition to said chambers, these latter partial or semi-partitions being intermediate those formed by the said narrow rings 35 and 37, as shown. In this way portions of the charges of the expansible propulsive agent which are forced through the injector-ports of ring 5 by pressure are caused to flow laterally on opposite sides of the central plane of rotation of the impactwheel, substantially as indicated by the arrows shown in Fig. 6.

In the operation of the motor the pressure-chamber formed in the outer surface of ring 5, is kept constantly filled with the expansible propulsive agent under pressure, and charges of such agent are caused to be injected through said injector-ports, as is apparent, and the end walls of the pockets in the stationary rings of cylinder 17, constitute abutments or resistances whereby the impact-wheel is turned or propelled by direct impingement of the charges upon the end walls of the rings on the wheel-rim, such impingement first taking place in the pockets of ring 5, where the main or initial force of impact of the charges is expended. While thus expending such force the charges successively received in the pockets of said ring 5, spread laterally of their own expansion and fiow in opposite directions with respect to the central plane of rotation of the wheel, and

the separate portions of such charges pass over and under the partitions formed by the several narrow rings described, substantially as indicated, and in transit these charge-portions continue to act by impingement and reaction upon the end walls of the pockets of the rings on the wheel-rim, until finally the said chargeportions pass into the exhaust-chamber through the conduits or ports in the rings 15, on the rim, and the straight or radially disposed walls of the pockets of the stationary rings 33, serve as abutments or resistances by which the wheel 0 is further assisted to be propelled by reaction of the charge-portions, as will be fully understood.

As shown in Fig. 1, the shaft B is also supported in outer bearings 50, at the upper ends of standards or uprights 52,,said shaft being provided with a pulley 53, for suitable connection therewith of a belt to be driven from the motor. 1

It will be understood that various changes or alterations may be made in the form or embodiment herein shown without departure from the spirit or scope of my invention.

It will be noted that I have provided a rotating member within a casing, and that upon this rotating memher I have located a plurality of rings each two of which is divided by partitions which extend outward from the periphery of the rotating member. In like manner the interior of the casing is also provided with rings and partitions which are so located as to come between, substantially about midway, the partitions herein first mentioned. All of these partitions are of substantially equal length, as for instance seen in Fig. 2 of the drawings. All of the rings aforementioned are provided with recesses, which are preferably inclined, and these recesses form series of rows of courses through which the propulsive agent must pass. The arrangementof the partitions as hereinbeiore specified is such as to render the course irregular or wavy so as to force the propulsive agent up and down or sidewise in its travel through the course.
